[LargeFormat] James Millen flash

[LNphoto]

The latest idea I've had to threaten my life is to resurrect this half 
of a James Millen electronic flash unit.

I've never heard of James Millen either, I have no idea when or for how 
long he was in business.  I don't even have the battery case that this 
should go to.  The only part of the puzzle I have is what is stamped on 
the lock ring:   "James Millen Malden, Mass" and the fact that the 
innards look similar to my dad's old Atwater Kent radio--wax covered 
condensers, cotton covered wire, etc , so I doubt this is post war, or 
if it is, it isn't by much.
Now Malden Mass isn't too far away from Boston, Mass Institute of Tech 
and thus Doc Egerton, another guy that like to live with bottled 
lighting.  There may be a connection I don't know.

While I'm daring, foolish and even crazy, I know better than to try to 
put high voltage to what you see in the photos, so my idea is to use a 
modern flash unit---- a Norman 400B  to power the tube.   The trouble 
is I have no idea what this lovely tube can handle.  If the power 
supply is greater than the tube, will the tube go or would the power 
supply fail after a while.

So now to the questions.

the historical one first:  Any body know about (who what when where) 
James Millen of Malden Mass?

Then the techincal:  anybody no of a person, place or thing(webpage or 
book) that might have the specs on a Sylvania R4330 Xenon Flash tube?
